Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

Location & Local Information
Velký Tisý is a small pond located in the South Bohemian Region of the Czech Republic, surrounded by natural meadows and forested areas that create a tranquil environment. Due to its shallow depth, the water warms up fairly quickly during the summer months. In July and August, water temperatures typically reach around 20–22 °C, making it comfortable for swimming, wading, and light recreational activities. Its calm waters and gentle shoreline make it suitable for families and casual swimmers.
Swimming at Velký Tisý is mostly informal, with natural banks rather than developed beaches or commercial facilities. Visitors often combine a swim with sunbathing, picnicking, or short walks in the surrounding countryside. The quiet setting and scenic surroundings provide a relaxing atmosphere, making it a pleasant spot for locals and visitors seeking a peaceful place to enjoy the water.
Outside the peak summer period, water temperatures drop noticeably. In May or September, the pond usually remains around 14–16 °C, which is too cool for prolonged swimming but still allows for brief wading or splashing along the shore. Even when the water is cooler, Velký Tisý remains an attractive destination for enjoying nature, birdwatching, or simply relaxing in the calm South Bohemian landscape.
